The 2MM9118WI DUL is a super-precision angular contact ball bearing supplied as a duplex universal matched set of two bearings with flush-ground faces. This set features a 90mm bore, 140mm outside diameter, 48mm total set width, 15° contact angle, and maximum-capacity internal design suitable for low to moderate speed applications. Manufactured to Timken P4S precision class with ABEC 7 dimensional tolerances and ABEC 9 running accuracy, the set includes light preload and open construction without seals or shields.
Super-precision angular contact ball bearings in duplex universal arrangements are typically used in machine tool spindles, precision gearboxes, and high-accuracy rotary applications where rigid shaft support and precise positioning are required. The universal mounting flexibility allows configuration as back-to-back, face-to-face, or tandem depending on load direction and stiffness requirements.
